A second implantable deep brain stimulation device for patients with Parkinson disease or essential tremor has received FDA approval.
The Brio Neurostimulation System from St Jude Medical in St Paul, Minnesota, is a small, battery-powered, rechargeable electrical pulse generator implanted in the upper chest with wire leads that attach to electrodes placed in specific locations of the brain, depending on whether it’s used to treat Parkinson disease or essential tremor (http://1.usa.gov/1Bc5ptq). The generator delivers continuous, low-intensity electrical pulses to target areas in the brain, and clinicians can adjust it to optimize its benefits.
